| 1 | Recent progress of integrated circuits and optoelectronic chips显示文摘Integrated circuits(ICs)and optoelectronic chips are the foundation stones of the modern information society.The IC industry has been driven by the so-called'Moore's law'in the past 60 years,and now has entered the post Moore's law era.In this paper,we review the recent progress of ICs and optoelectronic chips.The research status,technical challenges and development trend of devices,chips and integrated technologies of typical IC and optoelectronic chips are focused on.The main contents include the development law of IC and optoelectronic chip technology,the IC design and processing technology,emerging memory and chip architecture,brain-like chip structure and its mechanism,heterogeneous integration,quantum chip technology,silicon photonics chip technology,integrated microwave photonic chip,and optoelectronic hybrid integrated chip. | Yue HAO Shuiying XIANG Genquan HAN Jincheng ZHANG Xiaohua MA Zhangming ZHU Xingxing GUO Yahui ZHANG Yanan HAN Ziwei SONG Yan LIU Ling YANG Hong ZHOU Jiangyi SHI Wei ZHANG Min XU Weisheng ZHAO Biao PAN Yangqi HUANG Qi LIU Yimao CAI Jian ZHU Xin OU Tiangui YOU Huaqiang WU Bin GAO Zhiyong ZHANG Guoping GUO Yonghua CHEN Yong LIU Xiangfei CHEN Chunlai XUE Xingjun WANG Lixia ZHAO Xihua ZOU Lianshan YAN Ming LI | 2021 | Science China(Information Sciences)2021，64，10： | 7 |
| 2 | Role ofβ(FeA1)nanoparticles in abnormal grain growth in the annealing of cast Cu-Al-Mn-Fe shape memory alloys显示文摘In this study,the low-cost production of Cu-AI-Mn-Fe shape memory alloy single crystals exceeding 46 mm by abnormal grain growth was realized only through annealing their cast alloys.The results show that the mis-orientation formed during annealing may be responsible for such abnormal grain growth process.It was con-firmed that this misorientation resulted from the dissolution of bec B(FeAI)nanoparticles during heat treatment at a sufficiently temperature of approximately 1173 K.The rate of migration of the abnormal grain boundary was experimentally measured to be approximately9.3 x 10^-m s^-1within 2 min of the commencement of abnormal grain growth.Additionally,the range of composition of the alloys that can lead to abnormal grain growth was determined.When the Cu-13.0AI-6.5Mn-3.2Fe single crystal close to the[100]direction was deformed to a pre-strain of 12%,full shape recovery happened without any residual strain.At that time,the superelastic strain was approximately 9%.Such a superelastic characteristic remained nearly constant over 50 cycles,showing excellent fatigue resistance.The superelastic properties of the present Cu-13.0AI-6.5Mn-3.2Fe single crystal are compared to those of commercial Ni-Ti-based shape memory alloys.Therefore,it can be considered as a new kind of superelastic material having practical applications.The obtained results should be of great significance in the development of Cu based shape memory alloys.Furthermore,it is expected that a similar microstructure can be designed for the production of more metallic single crystals. | Shuiyuan Yang Xinyu Qing Jixun Zhang Lipeng Guo Shen Hong Mingpei Li Jinbin Zhang Cuiping Wang Xingjun Liu | 2020 | Progress in Natural Science:Materials International2020，30，4： | 2 |

| 5 | Microstructure, martensitic transformation and shape memory effect of polycrystalline Cu-Al-Mn-Fe alloys显示文摘In this study, two Cu-Al-Mn-Fe polycrystalline alloys were prepared, and their microstructure, reversible martensitic transformation, mechanical properties and shape memory effects were investigated. The results show that the reversible martensitic transformation temperatures of the studied alloys are between room temperature and 373 K, which are suitable for practical applications. Two typed martensites of 18R and 2H coexist both in two alloys. The bcc β(FeAl) nanoparticles are Fe-rich, Mnrich and Cu-poor, whereas the martensite is Cu-rich, Fe-poor and Mn-poor. The size of nanoparticles ranges from tens to hundreds of nanometers. Full shape recovery property is displayed in Cu-12.9Al-4.5Mn-2.6Fe alloy all the time while applying different deformation from 5% to 8%. The maximum recoverable strain is up to 4.4% with a recovery rate of 100%. | YANG ShuiYuan HONG Shen LI MingPei QING XinYu GUO LiPeng GUO YiHui WANG CuiPing LIU XingJun | 2021 | Science China(Technological Sciences)2021，64，2： | 0 |
| 6 | Excellent shape recovery characteristics of Cu-Al-Mn-Fe shape memory single crystal显示文摘Shape memory alloys can recover the deformed shape due to their superelasticity or shape memory effect. In this study, a novel Cu-Al-Mn-Fe shape memory single crystal is reported. The results show that it has excellent superelasticity and shape memory effect simultaneously when deformed at room temperature, as well as tunably wide response temperature range with near-zero interval of reverse phase transformation. When deforming one single crystal at room temperature, it not only possesses full superelasticity of 7%, but also tunable shape memory effects up to 8.8 %. The full shape recovery during heating exhibits near-zero response interval and tunably wide response temperature range of 166 K depending on the deformation. The functional characteristics of the alloys result from the controllable reverse phase transformation hinging on the stabilization of stress-induced martensite. This class of Cu-Al-Mn-Fe alloy may be used as both superelastic materials, and shape memory materials with wide working temperature range as high-sensitive detector, driver or sensor. | Shuiyuan Yang Lipeng Guo Xinyu Qing Shen Hong Jixun Zhang Mingpei Li Cuiping Wang Xingjun Liu | 2020 | Journal of Materials Science & Technology2020，54，22： | 0 |
